Evidence notes
Barley grass contains beneficial nutrients and some in vitro antioxidant studies exist, but human clinical trials are sparse and most health claims lack robust RCT evidence. Traditional use is well-established but not strongly validated scientifically.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
